This paper theoretically analyzes and empirically investigates the importance of local interaction between individuals of different linguistic groups for the provision of public goods at the national level. Depending on whether local interaction mitigates or reinforces antagonism towards other...

We investigate the empirical relationship between ethnicity and culture, defined as a vector of traits reflecting norms, attitudes and preferences. Using surveys of individual values in 76 countries, we find that ethnic identity is a significant predictor of cultural values, yet that...

This paper analyzes whether the propensity to secede by subnational regions responds mostly to differences in income per capita or to distinct identities. We explore this question in a quantitative political economy model where people's willingness to finance a public good depends on their...

Culture has played a pivotal role in human evolution. Yet, the ability of social scientists to study culture is limited by the currently available measurement instruments. Scholars of culture must regularly choose between scalable but sparse survey-based methods or restricted but rich...

This paper uses a linguistic tree, describing the genealogical relationship between all 6,912 world languages, to compute measures of diversity at different levels of linguistic aggregation.By doing so, we let the data inform us on which linguistic cleavages are most relevant for a range of...

This paper proposes a new method to measure ethnolinguistic diversity and offers new results linking such diversity with a range of political economy outcomes -- civil conflict, redistribution, economic growth and the provision of public goods. We use linguistic trees, describing the...

We consider a linguistically diversified society and examine the notion of language disenfranchisement when some individuals are denied the full access to documents and political process in their native tongues. To calculate the disenfranchisement indices we use the Dyen percentage cognate...

We suggest a demand model for foreign languages and estimate demand functions for English, French, German and Spanish in 13 European countries. We show that three variables explain reasonably well the share of people who learn a foreign language: the larger the native population in the country,...
